DOF full frame vs. crop sensor

[btaylor]

DOF is a hard one to quantify as it really is subjective. What you consider effective out of focus blur might be different to somebody else.


From real world experience - going from a crop body to a 5D Mark II, the difference is very significant.

so would be easier to achieve OOF blur on a FF or crop sensor body?? with same lens of course....

To put it simply, FF gives more OOF blur.

That sure was simple

Though it might seem obvious, I'd like to mention that the OOF blur is the same when DOF is the same. If you stop down with your crop camera, you'll get no DOF advantage shooting full frame (you'll just stop down more).

Isn't DOF just a distance? Like, "4 inches", with a given COC. How is that hard to quantify or subjective? (Though I agree, the question of what is effective is subjective).
